SPECIFICATION forming part of Letters Patent N 0. 703,182, dated June24, 1902.

Application filed May 31, 1901. Serial No. 62,627. (No model.)

To etZZ 107L071? it may concern:

Be it known that I, AUGUSTUS JOHNSON, a citizen ofthe United States,residing at Falun, in the county of Saline and State of Kansas, haveinvented a new and useful Band-Cutter and Feeder-for Threshing-Machines,of which the following is a specification.

My invention is an improved band-cutter and feeder forthreshing-machines; and it consists in the peculiarconstruction andcombination of devices hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a top plan View of a band-cutter and feederfor threshing-ma chines constructed in accordance with myinvention. Fig.2 is an end elevation of the same. Fig. 3 is a vertical sectional viewtaken on a plane indicated by the line a a, in Fig. 1. Fig. 4 is avertical longitudinal sectional view taken on a plane indicated by-theline b b in Fig. 1 and showing the arrangement of the band-cutter andfeeder with reference to the threshing mechanism. Fig. 5 is a detailperspective view of the scatteringgrate.

In the embodiment of my invention I provide a feeder-frame 1, whichcomprises the parallel sides 2 andis adapted to be attached to the frontend of a threshing-machine. In Fig. 40f the drawings aportion ofathreshingmachine is indicated at A. In the sides2 are journaled a pairof shafts 3 4, which are respectively provided with sprocket-wheels 3and 4. Endless sprocket-chains 5 connect said sprocket-wheels, and saidsprocket-chains are connected together by transversely-disposed slats 6,which are disposed at suitable distancesapart. Thesaid chains andslatsconstitute an endless traveling main con veyer. At the inner end of themain conveyor, between the same and the mouth B of the threshingmachinecasing, is disposed an auxiliary conveyer 7. The same comprises a pairof shafts 8,sprocket-wheels 8 on said shafts, endless sprocket chains 9,which connect said sprocket-wheels, and slats 10, which connect saidsprocket-chains. The said auxiliary conveyer is inclined at a suitableangle and extends upwardly to the threshing mechanism, as shown in Fig.4, and the lower side thereof is under the discharge side of the mainconveyor, so that the grain falls from the latter onto said auxiliaryconveyer. Thearrows in Fig. 4 indicate the direction of movement of saidconveyers. The shaft 3'is provided at one end with a power-pulley 11.Said shaft is further provided on opposite sides of the frame 1 withmiter gear-wheels 12 13. Shafts 14 15 are jour'naled in bearings 16 onopposite sides of the frame 1, said shafts being disposed longitudinallyof said frame and in a horizontal position. At the rear end of shaft 14is a miter gear-wheel 17, that engages the gear 12. Shaft 15 has at itsrear end a miter gear-wheel 18, that engages the gear 13. Thereby poweris conveyed from shaft 3 to shafts 14 15, as will be understood; Each ofsaid shafts 14 15 has at its front end a crankwheel 19. The shaft 14 isfurther provided with a sprocket-wheel 20.

A hopper 21 is disposed transversely on the frame 1, and the ends ofsaid hopper-frame project beyond the sides of said frame 1. A bar 22connects the central portions of the sides of the hopper-frame 21 and isdisposed at a suitable distance above the central portion of the mainconveyer. The said bar 22 carries the bearings for a pair ofsprocketwheels 23 24, which are under said bar. The vertical shaft ofsprocket-wheel 24 has at its upper end a miter gear-wheel 25. The sameis engaged'by a similar gear 26, that is fast on a shaft 31, which isjournaled in bearings 32 on the sides of the hopper-frame. At the frontend of said shaft 31 isa sprocket-wheel At the rear end thereof is asimilar sprocket-wheel 34. The latter is connected to the sprocket-wheel20 on shaft 14 by an endless sprocket-chain 35. Thereby power isconveyed from said shaft 14 to said shaft 31, from the latter throughthe gears hereinbefore described to the sprocket-wheel 24, whichsprocket-Wheel 24 is connected to the sprocket-wheel 23 by an endlesssprocketchain 36. Said sprocket-chain is provided with a series ofband-cutting knives 37. Said sprocket-chain and band-cutting knivesconstitnte an endless traveling band cutter, which is disposed at asuitable height above the central portion of the main conveyer.

A pair of cranked rock-shafts 38 are journaled in hearings in a pair ofbars 39, which connect the sides 2 of frame 1 together and are disposedabove the outer portion of the main conveyer. The said crankedrockshafts are connected together by a pair of bars 40, which aredisposed transversely with relation to and above the main conveyer, andto the said bars 40 are secured the front portions of a series ofscattering grate-bars 41. Thereby a scatteringrate is formed which isdisposed above the mainconveyer and below the endless travelingband-cutter. Said scattering-grate, as will be understood, is adapted tomove back and forth in a lateral direction over the main conveyer.Motion is communicated to the said scattering-grate by pitmen 42, whichconnect the cranks 19 on the shafts 14 15 to one of the bars 40 of saidscattering-grate, as is shown in detail in Fig. 5. The function of thescattering-grate is to support the sheaves while the bands are being cutand scatter and loosen the grain and cause the same to fall evenly ontothe main conveyer, so that the grain will 'be evenly carried by the mainconveyer to the auxiliary conveyer and by the latter delivered'tothethreshingmechauism. Furthermore, the scattering grate bars serve todispose the grain longitudinally on the main conveyer.

In opposite ends of the hopper-frame are disposed a pair ofsheaf-feeding conveyers 43 44. The feeder-conveyer 43 comprises a pairof shafts 45 46, sprocket-wheels 47 on said shafts, endlesssprocket-chains 48,which connect said sprocket-wheels of said respectiveshafts, and cross-slats 49, which connect said sprocket-chains'together.The shaft 45 of feeder-conveyer 43 has at its front end a sprocket-Wheel50. The feeder-conveyer 44 comprises a pair of shafts 51 52,sprocketwheels 53 on said shafts, endless sprocketchains 54,whichconnect said sprocket-wheels of said respective shafts together, andcrossslats 55, which connect said endless sprocketchains together. Atthe front end of shaft 51 isasprocket-wheel 56. An idler sprocketwheel57 is journaled on a suitable spindle 58, which projects from the frontside of the hopper-frame at a suitable distance to one side of the shaft45. An endless sprocketchain 59 connects the sprocket-wheel 53, theidler-wheel 57, and sprocket-wheel 56 together and passes under thesprocket-wheel 50. Thereby power is conveyed from the shaft 31 to thefeed-conveyers 43 44, and the latter are driven in opposite directions,as is indicated by the arrows in Fig. 3. The upper leads thereof traveltoward the endless travcling band-cutter, which is disposed at a pointmidway between said feed-conveyer. The sheaves are thrown onto saidfeed-conveyers and are by the latter conveyed to the band-cutter, theoperation of which has been hereinbefore described. The relativedisposition of the band-cutter, sheaf conveyers 43 44, and grate is suchthat the sheaves while the bands thereof are being out are on said grateand between said band-cutter and the the unbound grain evenly andwithout choking to the threshing mechanism.

A revoluble beater and feeder 60 is disposed above the upper side of theauxiliary conveyer in operative relation thereto and may be driven byany suitable means. The shaft of said heater and feeder is journaled inbearings which are movable verticallyin suitable guides 61. Springs 62while serving to normally depress said bearings and the feeder andheater enable the latter to rise as grain passes under the same. Saidfeeder and beater, as will be understood, serve to facilitate thefeeding of the grain to the threshing mechanism.

Having thus described my invention, I claim 1. The combination of aconveyer, a scattering-grate disposed above the same and adapted forreciprocating movement, transversely-oscillating shafts having crankssupporting and connected by said grate, and means to impartreciprocating movement to the latter, and thereby impart oscillatorymotion to said crank-shafts, substantially as described.

2. The combination of a conveyer, a seattering-grate disposed above thesame, a bandcutting mechanism above said grate and a sheaf-conveyer toconvey sheaves to said band cutting mechanism, the relative dispositionof said cutting mechanism, grate and sheaf-conveyer being such. that thesheaves, while the bands thereof are being cut, are on said grate andbetween said cutting mechanism and sheaf-conveyer, substantially asdescribed.

3. The combination of a conveyor, a seattering-grate above the same, anendless traveling band-cutte r,horizontally disposed above said grate,and a plurality of sheaf-conveyers with their inner portions oppositethe leads of said band-cutter, the relative dispositions of said grate,band-cutter and sheaf-conveyers being such that the sheaves, while thebands thereof are being out are on said grate and between saidband-cutter andsheaf-conveyers, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

AUGUSTUS JOHNSON.
